Methodological Rigor and Experimental Validation Questions

Cover experimental design and validation best practices and the trade offs between novelty and reproducibility. Topics include selection of controls and baselines, primary and guardrail metrics, ablation studies, error analysis, statistical significance and confidence in results, reproducibility practices, robustness checks, and avoidance of common pitfalls and biases. Also demonstrate critical thinking by proposing alternative approaches and diagnostics when initial results are inconclusive. Interviewers will probe for concrete validation strategies and an ability to justify methodological choices.
